Occurrence
edit5-Methylfurfuryl alcohol naturally occurs as one of many volatile compounds present in Nicotiana tabacum, or cultivated tobacco. The compound appears at much lower concentration in tobacco leaves than the more common aldehyde furfural.[3]
As the reduction product of 5-methylfurfural, 5-methylfurfuryl alcohol occurs in barrel-aged wines along with 5-methylfurfuryl ethyl ether.[4]
Synthesis
edit5-Methylfurfuryl alcohol can be produced through a reduction of 5-methylfurfural with lithium aluminium hydride,[4] though historically the reduction has been performed starting with methyl 5-methyl–2-furoate rather than 5-methylfurfural.[6]
